IMPROVEMENT IN TUGK-UREASER FOR SEWING-MACHINES;

TO ALL WHOM IT MAY- coroner:

Be it known that we, AARON MOREHOUSE and ALFRED R. HEATH, of vDanbury,in the county of Fairfield, and State of Connecticut, have invented anew and useful Improved Tucker or Plaiter for Sewing-Machines; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making part of'this specification, in which- Figure 1 is a perspectiveview.

Figure 2 is an elevation of the folder and guide, and

Figure 3 is a perspective view of the finger. t v

The same letters employed in the several figures indicate the sameparts.

This folder and tucker is intended for attachment to the Wheeler andWilson and other sewing-machines.

A is a presser -piston, to be attached in place of the ordinary'presser-foot and piston of the machine, in

such manner that the hole 13 shall coincide with the middle holein theplate. Gis the upright arm, constructed with a. slot, D; as shown, thecentre of the widest part of the slot being on a lindwith theneedle-hole B the direction of the line of action of thefeeding-mechanism of the machine, the slot gradually tapering towardsthe needle hole, and there curvingto one side to carry the upn'er.portion of the tuck or plait out of the way of the'needle.

V E is a stud, projecting from the top of the arm G, and havingnvertical hole through it to receive lone leg of th-e spring-presser F,to the opposite leg of which is attached'a foot, in the form somewhat ofan inverted letter U. Another hole horizontally through the stud Ereceives the arm G, fixed by a set-screw; The guide H is a thin, curvedpiece, attached to the arm G by a set-screw, and the marker I issimilarly attach-ed to the other end of the said arm G. This marker isconstructed with a spring-clutch to receive a pencil to be used as amarker or pointed feed-bar, as will be explained. J is a spring-guide,forming part 0t the arm or plate 0, and having a spring fastened to itwhich extends under the folder to the hole B. p

The finger K is attached by a screw to the rear left-hand screw-hole ofthe top of the plate, with the curved end to the rear. The boss L has ahole through it to receive the centre-rod M, fastened by aset serew. Nis a bar, working on the rod M as a pivot, and. extending within theslot D. A swell at O is made on the 1 bottom of the arm 0, with astraight edge extending along the said plate on a line with the edge ofthe hole B,

toform a guide for the folded edge of the goods, which is pressedagainst it by the spring J, to secure the penetration of the goods bythe needle.

The folder and guide being attached to the machine, and.also thefinger.K, the end of the bar N should be elevated ashighfrom themachine-plate as the width of tbercquired tuck, and there secured by theset-screw. The spring-presscr F should then he slid nearly down to thebar N.

The marker or feed-hand I should then be so set that the point shouldstand at such an angle with the plate as not to retard the movement ofthe cloth, but rather to assist the feed, and in such position laterallythat the point shall mark the line designed for the folded edge of thenext succeeding tuck. The guide H need not be used .in making the firsttuck, unless the line of the folded edge of the tuck-(before it isfolded) is at no greater distance from the corresponding and paralleledge of the fabric, or some defined parallel line thereon, than thedistance from the'bar N to the rear or front edge of the plate, of thesewing-machine. In such case the guide H can be used as a'gauge forguiding the'fabric in making the first tuck, it not being then necessaryto mark the line of the first tuck by hand. It is only necessary to markthe first tuck, as the'maiker or guide afi'ords suflicient guides forall succeeding parallel tucks, except in case the tucks are so far apartas not to permit their use. In the latter case the parallel line must bemarked.

Inoperating the tucker, the fabric lying flat atthe left of the operatorshould be drawn to the right, towards the needle, in such manner that itshall pass over the bar N, the point of the latter coming directly underthe line desired for the folded edge of the first tuck, the foot of thespring-prcsser F pressing gently upon the part of the fabric forming thefolded edge. The needle being out of the plate, and folderandprcsscrpiston down, they rest upon the feeder of the machine,'so thatthe folder does not rest upon the plate.- This allows the folded edge ofthe goods to be drawn to the right to the feeder. Then, raising theresser-piston very slightly, the goods should be drawn under the needleholeB, and 'the'prcsser-piston dropped. The springguide J will now pressthe lower part of the tuck together, so as to insure the needle passingthrough the edge. The machine may theube operated in the usual manner,the feeder drawing the goods to the needle, the downward pressure of thespring-presser F, and the'pe'culiarshape of the lower part'of the slotD, combining to prevent the tuck becoming wider than at first, while"the upward support of the bar N prevents it from becoming narrower, andthe sprin -guide J insuring the penetration of the edge by the needle,while the pencil on vthe marker I marks a line or succession of dotsparallel with the line of stitching. This'arra'ngement enables.

the operator to make accurately-parallel tucks, either straight orcurved.

The succeeding tucksare madeby causing the marked line to pass over the,point of'the bar N, or, in case the marker has not been used, the guideH shouldbe placed over or nearly touching the line of stitehing orfoldededge of the previous tuck, at the desired distance from the fingerN.

Having fully explained the construction and mode of operatingourimproved tucke what we claim as our invention,- and desire to secureby Letters Patent, is

1.' The bent arm C attached to the presser-piston A, when constructedwith the slot D, needle-hole B, spring-guide J, and guide-swell O,substantially as and for the purpose set forth. I

2. The combination of the lotted arm C, constructed as described, withthe adjustable bar N, and springp'resser F, as set forth.

3. The combination of the presser-piston A, slotted arm 0, spring-guideJ, guide 0, and spring-presser F, with the adjustable guide H or markerI, arranged to operate substantially as described.

In testimony whereof, we have signed our names to this specification inthe presence of two subscribing witnesses. v
